How do I replace null value in Pivot?

[juzzbitzz]

I have a pivot table that has a null value for a few of the records in the "Date" column that is preventing me from sorting the table. How and with what do I replace the null value in the Date column?

You have 3 options:

...  | eval Date = coalesce(Date, yourAlternateFieldHere, "Your Hard-Coded Default Value Here")

OR

...  | fillnull value="Your Hard-Coded Default Value Here" Date

OR

...  | filldown Date

I leave it as an exercise for the reader to figure our (or @DalJeanis to explain) the differences.

You need to populate the Date field.

Identify, on the records with no Date, what is a good candidate for substitution, then do something like

| eval Date = coalesce(Date,mySubstituteField)

@juzzbitzz,

Try adding |fillnull value="your value for date" Date in the base search before aggregation/sort
